LOCK.

Application led March 31, 1.923. Seri-a1 No.'629,009.

T all wwm t may concern:

Be it known that I, BENJAMIN II. LEvIN, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Locks, of which the following is a specification.

My invention relates to improvements in locks and more particularly Vto spring locks adapted for use on canteen bags, suitcases, and the like, and has for an object to make such a loekin which the bolt operating mechanism is housed in a .small casing on top of the lock and only the locking bolt is mounted beneath the top plate of the lock within the contines of the depending flanges of the lock, so that no portion on the under side of the lock protrudes or needs to be set into the bag or case.

Another object is to make the eye portion of the hasp device integral with the hasp plate or strap, instead of riveting said eye portion on said hasp plate as in the usual 5 types of construction.

. Another object is to provide aninexpensive, durable and eiii'cient lock of this kind.

Other objects will appear hereinafter. The invention consists in the combinations and arrangements of parts hereinafter described and claimed. y I

The invention will be best understood by reference to the accompanying drawings V forming a part of this speciiication, and in which, j

Fig. 1 is a plan View of my lock mounted in position on a canteen bag a portion of which is shown;

Fig. 2 is an inverted view of the lock;

VF ig. 3 is a cross section taken on line 3-3 of Fig. 1;

Fig. 4 is an enlarged, inverted partial view of the lock with the locking bolt removed; v

Fig. 5 is an enlarged sectional vlew on line 5--5 of Fig. 4, and

Fig. 6 is a view of the key. .l In the drawings, 10 represents a portion of a canteen bag or suit case to which the main portion 11 of my improved lock is fastened, as by means of rivets 12 or the like. The lock also includes the hasp device havingan attaching plate 13 mounted on the cover 14 ofthe bag 10, as by means of rivets 15 or the like. y The main portion 11 of the lock comprises a top plate 16 with anges 17 extending'at right angles from the edges of said plate,

thus substantially forming a housing. Lugs 18 are turned inward from the lower edges of the flanges 17 for retaining' and guidin the locking plate or looking bolt 19 between said flanges, and a spring 20 has the en'd'20 of one arm engaging in an opening in the by a lug 21 on the flange 17, said spring automatically holds said boltin locking position. Said locking bolt and spring are thus entirely contained or housed between flanges 17 and no part of the lock protrudes beneath the lower edges of said flanges,-but the flanges are seated directly on the can.- teen bag and no opening needbe provided pnlt-he bag for any protruding part of said plate 19 andthe end of the other armheld v A small casingV 22 is mounted on the topy plate 16 of the lock by means` of a pairof integral lingers 23 which extend through and slide in enlargedslots 24 provided in the top plate 16, and pass throughclose ittingy slots 25 in the locking bolt119, the'ends of said fingersbeing bent over against-the lower side of said bolt 19. s

The mechanism for operating the locking bolt is housed in said-*casing 22 and includes a circular disc 26 having a smaller circular portion 27 which extends partly between fingers 23. A pin 28 extends from said portion 27 and operates in an irregular slot 29 provided in the top plate 16, said slot having a laterally extending narrow portion for receiving said pin to hold the plate 19 in locking position, and a longitudinally eXtending portion 29 which is parallel with the Slots 24 and in which saidlpin moves while the lingers 23 move longitudinally in Athe elongated slots 24 in plate 16 when the locking plate 19 is slid longitudinally into lpcking and unlocking position. A pin 30 Vis provided on the upper face of the disc 26 and extends into the casing 22 to be engaged by the web 31 of the key 32. The key is insei-ted through the key hole 33 in the casing 22, and the lower end or pin^34 of the `key stem engages in the opening 35 in the disc 26 and in the opening 36 in the locking bolt 19, and moves longitudinally through the elongated slot 37 in the top plate 16, while said key carries with it the casing 22, as the locking bolt 19 is being operated. A coil spring 3S holds the disc firmly in set position and also resiliently to permit said disc to move slightly upward to free the side notch 39 of the disc from the bent portion of the linger 23, in order to move the device out of the released position into the illustrated locked position.

The hasp device which has its attaching plate 13 fastened to the covering 14 of the bag, comprises a hasp plate or strap 40 pivotally mounted on said attaching plate by means of a rivet 41 passing through ears 13 and 40 provided on said attaching plate and said strap portion, respectively. A coil spring 42 normally moves and retains the strap 40 in released position. The lock engaging eye portion 43 of the hasp device is made integral with the movable strap 40 and is bent back upon the part 40 and then bent downwardly to form a ledge or flange 44 for covering` the slot 45 in the top plate 16, through which slot the eye portion 43 extends, and receives the locking tongue 46 on the bolt 19 to hold said hasp in locked position.

Vhile I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having described my invention what I claim as new and desire to secure by Letters Patent, is:

1. A lock comprising a top plate with downwardly extending flanges, a locking member mounted between said flanges, a casing movably mounted on said plate, means on said casing and extending through said plate for engaging and operating said locking member, and a key operated member mounted in saidV casing and having means movable in one part of a slot in said plate to hold said locking member looked and movable in another part of said slot to permit release movement thereof.

2. A lock of the class described comprising a top plate with downwardly extending flanges, a locking member mounted between said flanges and retained therein by inwardly bent lugs at the lower edge of said flanges, a spring having one arm held by a lug on said flange and having another arm engagingnin an opening in said locking member tov normally move said member into locking position, and a casing on said top plate with means movable in an opening in said plate to lock said member in position.
